working well-summer 2019 current temps in europe may reach 40c and here in usa already 37c and uv at 11.5 so this is a gr8stream of insight into what and how-why-physiological adaptation-behavioral changes of that ole dilation -thermodynamics of releasing the sweat gland thru the blood flow exit detox and water loss-so keep fluid intake up and add electrolytes-nice insight on dry vs humid environments-liquid2vapor and heat energy of latent evaporation- people who cant sweat should take quick cool showers outside in sun-to rebalance works out here in so ea az desert-very cool share-manythxs

thank you so much! this helps me a lot!

Very organized explanation. Thank you very much.

Best explanation,love learning from you

+Dr John Campbell When you have an infection why can your temperature start to go the other way as is too low (without medication and without naturally overcoming the infection). Is this a sign the infection has progressed to a new stage?

Love you Sir, Super Explanation..... :)

what about superficial veins enlargment is it a mechanism or is it secondary to the arteriolar vasodilation ?

Awesome explaination

Thanks so much dr.compbell

Thank you , sir !

Thank you so much Sir for the great explanation. May God bless you.

Thanks a lot!

All your videos are of great use, many thanks. One question I have is why do we give anti pyrexia drugs to sick patients? Is this not counter productive?

EXCELLENT

+Dr John Campbell Does it mean that when we feel so uncomfortably hot during fever (and we havent taken medicine), the body has overcome the infection and lowered the set point? Also, till when should the elevated set point be left uninterrupted and when should one take medicine?

dammm dr cambell back at it again with them great vids

super helpful!!!!

thankyou very much dr cambell for this vedio. i m 35 y/o m. i suffehyperhydrosis generalised hyperhydrosis. i cannot bear temperature more than 22 centigrade. i sweat non stop very fast. can u plz help me to kn why my body cools me when its only 22 degrees. life is too much hard with this tremendous sweating. my all harmones . brain mri are nor. i dont have any chronic diseases. plz explain how to not sweat?. thankyou sir.

Very good presentation sir

Excellent

Dr Campbell what is occurring in the body when a person experiences a hot flash such as in the beginning of menopause?

excellent!

Does this mean we should not give antipyretics if a patient has a fever and they are having a rigor?

Nice explanation sir From india

What's real functions of a prostaglandins? Because it's included in peptic ulcers

thank you dad

I have a TBI from a head on collision 7 years ago ....I began to notice I could no longer tolerate warm to hot temperatures above 90 degrees . after 2nd covid infection in sept 2020 it hit my brain and after now I cannot take any heat over 75 degrees . it feels like 100 plus ., producing a heat stroke type reaction . i have to stay inside summers with air conditioning. this has made my life very frustrating . Can you tell me what has happened ...?

If you feel so hot but your skin feels so cold! What's wrong

Thank you sir

Sir,.. Does heat intolerance play a role here..

Good video but once I heard the nasal inhalations it's all I could notice.

37 degrees centigrade is considered normal so why are you using 35? The Thyroid gland is responsible for regulating body temperature. It also regulates the metabolism. The T3 is what the body actually uses. T4 converts to T3 in the liver. Doctors say that a small amount of T3 is produced by the thyroid gland which is pure poppycock. That would interrupt the hypothalamic feedback system. Low Thyroid causes low body temp which causes a person to feel hot all the time (The ignorant doctors tell you that you feel sensitive to cold which is backwards - Thermodynamics). It also can cause the arteries to clog faster due to lethargy of the metabolic system. Perspiration is used to assist in regulating body temperature. Severe cold can cause the body to eliminate liquid to prevent freezing. So, if you fall into cold water and get rescued, blankets and warm liquid is a must to replenish the needed fluids and bring the body temperature back to normal quicker. I wrote a Point Paper about the Thyroid. I have suffered needlessly at the hands of very ignorant doctors. I have Pituitary damage and have hormone deficiencies making my life miserable. Especially the ignorant doctors unable to understand the physiological processes of the human body. Refusing to listen to a patient and recognize physical symptoms can cause severe harm to a patient. Good day, sir.
